IMPROVEMENT IN RUBBER ovERsHoEs.

Specification forming part of Letters Patent No. 151,970, dated June 16, 1874; application tiled March 4, 1874.

To all whom t may concern:

Be it known that I, FRANK ELMER HALL, of Boston, in the County of Suffolk, State ot' Massaohusetts,have invented a certain new and useful Improvement in ltubberand later- Proof Oyershoes, ot' which the following is a description sufficiently full, clear, and exaet to enable any person skilled in the art or science to which my invention appertains to make and use the saine, reference being had to the accompanying drawing forming a part otl this specification, in which- Figure l is an isoinetrical perspective view of my improved protector. Fig. 2 is a vertical longitudinal section of a shoe provided with the protector.

Like letters refer to like parts in the different figures ot' the drawing.

My invention relates to rubber shoes designed vfor oyerwear; and consists in a shoe provided with a metallic protector, disposed in the heel of the saine, as hereinafter more fully set forth and claimed, the object being to pre-A serve the shape of the shoe, and increase its durability at that point.

The extreme simplicity ot niy invention renders an elaborate description unnecessary.

The protector is made ot' metal, and formed as shown in Fig. l, having an upriglrtilange, A, and horizontal tlange u., and maybe east or struck from thin sheet metal, as preferred. The flange A is tiaring, or stands at an acute angle with the ilange o. In Fig. 2, O is the body of the shoe, O the heel, and B B the lining.

The protector Ais introduced when the shoe is molded and before vuleanization, being placed at the junction of the upper O and sole or heel Cf, and between the outer and inner portions ot' the shoe, as shown, and the shoe is then completed by vuleanization.

It is well known that ordinary rubber oyershoes are rapidly eut out and destroyed by the nails in the heels of the inner boot or shoe; also, that they are liable to run over `or bag77 at the heel, and wea-r unevenly. These ditlieulties are entirely obviated by the protector, which not only keeps the quarter s ofthe overshoe expanded and in place, but also prevents the nails ofthe inner shoe from eut-ting through the heel or sole ofthe rubber.

The protector is valuable in all water-proof overshoes construeted of rubber; but is especially valuable in the lighter forms of rubber overshoes for the reasons stated.

Having thus described my invention, what I claim isln a rubber shoe, a metallic heel re-enforee, having an inwardly-projeeting Ilange to sus tain and protect the tread of the heel, and vulcanized between the inner and outer port-ions ofthe heel, as specitied.
